REMOVABLE CLOSURE FOE CONTAINERS.

' Specification of Letters Eatent. Patented Jan 1'? 1922 Applicationfiled November 8,1821. Serial nations,

To (ZZZ w from it may concern:

Be it known that I, ANTHONY Sonnnmnn, a citizen of the United States;and resident of li hippany, in the county of Morris and a State of NewJersey, have invented certain new and useful Improvements in RemovableClosures for Containers, of which the following is a specification.

i This invention relates to closures for containers and moreparticularlyto the type of closure which includes an inset friction cover; and hasspecial reference to the provision of a closure of this natureconstituting an improvement on the Removable closure for containersshown in my copcnding an 'cation, Serial No. 345,928, of December beinga co-pend'ng application. In my said co- )ending application,

Serial No, 3%,928, I disclose closure construction of the dished orinset friction type in which an integral portion of the coverila or sidewalls is extended inwardly to a lip adapted to be engaged for rethereon,the ei eniplification shown in .iginal bead located at the edge of thecover flange or side wall said head inset or rolled inovide the engaginglip. this latter construction suitably s intended function, 1 have foundin manufacturing the containers and clois on a very extensive scale thatthere certain disadvantages incident to the inrolling step of themarginal head in such construction, and that the cloucture may he morecheaply ohin quantity production by producing p in liife entnianner aswill be further description of the In the operation of ininwardly of thehead as co-pending case, besides rec al forming implements and oreratingstep, the head.

and varied in length insetting ste 3 is ofttirnes E1111 the necessityfor SQlQQtiOR the misfornied closures onerator, with a'resulting L 1 rto the cost of production, is a suit of experiments p rforms;

1.1:) 1919, the present application contniuation in part of the said Mthe closure by exerting an upward during extensive manufacture of theseclosures, I have found that in lieu of inturning the head to provide theho, that the lip may he obtained in an eillcient and simple man he; by'merely flattening orv mashing a portion th roof with the flattening ormashing effected preferably toprovide a fully inset lip. The fiatteninor mashing is effected in a simple operation, it having been found thatwith the lips so formed the closures may be manufactured at a reducedcost not only,

but that a stronger multi-walled lip is obtained, subject to lessdeformation when the closure removed forcibly from the. container inwhich it is tightly frictionally received The provision of an improvedclosure element with the lip so providedcomprehends the primedesideratum of my present' invention.

Other objects of my invention will be apparent from the followingdescription taken in conjunction with the accompanying drawing's, inwhich 7 Fi ure l is a perspective view of the container with my improvedclosure element applied thereto'and showing'themanner of removing thesaid closure element, and

Figure 2 is a fragmentary cross-sectional view in detail taken on theline E22, Figure 1.

Referring to the drawings, theclosure of my invention is intended foruse with a corn tainer such as 10 provided with preferably straight sidewallsterminating atthe upper end preferably in an outwardly rolled bead11. While I disclose my closure as applied to a. container having asmooth side wall free from inward oro'ections it will be an;

parent that any type of container having an opening for an insetfriction cover may be employed.

The cover of my present invention comprises the dished or inset closuregenerally designated as 12, having a preferably fiat bottom 13 and sidewall or flange portion which is adapted to be frictionally received bythe side walls of the closure 10 to form a tight fit therewith, thecover flange or sidewall 1d terminating at the upper edge in themarginal outwardly rolled bead 15. The cover bead 15 is adapted tocontact with the upper edge of the container walls and more specificallyin the present construction, with the container marginal bead il,'tliehead'll forming a seat for the closure the head 11 and the cooperatingmarginal bead 15 limiting the motionof the cover into the container.

For the purpose of roviding means adapted to be'engaged by tiie fingerfor moving the cover out of the container or removing the covertherefrom, a portion of the head 15 is flattened or mashed to providethe lip portion 16. The-flattening or mashing of the head is effected soas to preferably provide a completely inset lip 16, as clearly shown inthe drawings. When soflconstrncted or formed, a multi-walled lip iseffected which has been ilound strong and effective for the purposeintended, the lip resisting deformation when theffingers are insertedtherebeneathand when the cover is removed from the frictionallyretaining container Walls, it having been further found, as heretoliorereierred to, that the cost ot production or the closure is lessened bythe flattening or mashingcf the bead in the manner described. p

The manner of making and the manner oi: using my improved closure willbe fully apparent from the above detailed description thereof. It willbe further apparent that I have provided an improved closure which maybe produced cheaply and effectively in quantity production, providing aclosure having, moreover, a uniformly neat and attractive appearancewhich may be easily manipulated in use.

While I have described the preferred form and use oi" my invention, itwill be apparent that changes in tormand use may be madewithoutdeparting from the spirit of the invention, defined in thefollowlng claims.

I claim 1. Incombination with a container having an open end; of adished closure having a wall adapted to be placed in and frictionallyengage said open end, the dished closure being provided with a-marginalbead at the upper. edge of the side wall thereof, an integral portion ofthesaid bead being, flattened or mashed to provide an inwardly formedlip adapted to be engaged for removal of the closure by an upward pullthereon i 2. In combination witha container having an open end, of adished closure having a wall adapted to'be placed in and trictionallyengage said open end the dished closure being provided with an outwardlyturned bead along the upper edge thereof adapted to seat over the openend of the container to limit the motion of the closure into the container, an integral portion of the said head being flattened or mashedto provide an inwardly formed lip adapted to be engaged for removal ofthe closure by anupward pull thereon. r

In combination with a container having vertical straight side walls treefrom inward projections and open at an end and a dished cover forclosing the container, said cover including relatively flat bottomportion, a side wall substantially at right angles thereto and adaptedto frictionally engage the side walls of the container, an outwardlyextending bead along the upper edge of the side well adapted to engagethe upper edge of the container to limit the motion of the cover intothe container. and means for facilitating the removal of the cover,lsa1dmeans including a portion of said bead'flattened or mashed and inwardlyset, providing an inwardly directed multi-walledlip spaced-from thebottom portionof the cover and adapted to be grasped by the tingers toexert an upward pull thereon for removal of the cover.

Signed at New York City, in the county of New York and State or NewYork, this 7th day of Nov, A. 1)., 1921. a ANTHONY SCHNEIDER.
